Orang-Utan

The world's largest arboreal mammal, Bornean orangutans weigh up to 90 kg and spend most of their lives in the rainforest canopy of Borneo. Solitary and semi-nomadic, they build nightly sleeping nests in trees and forage for fruit, leaves, and invertebrates. Critically Endangered, with populations having declined by over 50% in the past 60 years due to deforestation from palm oil expansion and illegal hunting.

Eisbär

The largest land carnivore on Earth, polar bears can exceed 700 kg and are found across Arctic sea ice from Canada to Russia. Highly specialized marine mammals that rely on sea ice to hunt ringed and bearded seals. Excellent swimmers capable of covering vast distances in open water. Listed as Vulnerable, with populations under severe pressure from rapid Arctic sea ice loss due to climate change.
